BATON ROUGE – A homicide investigator with Baton Rouge Police has been arrested after authorities said he illegally bought painkillers over the Internet.

Cpl. John Dauthier was put on administrative leave after the arrest this morning, and department officials said an internal investigation is pending.

Dauthier is accused of buying the painkiller Tramadol over the Internet without a valid prescription; investigators believe he bought it for personal use, and not for resale or distribution.

Dauthier is a nine-year veteran of the police department and is assigned to the Homicide Division.

Dauthier was booked into the parish jail in suspicion of possessing a legend drug without a prescription and obtaining legend drugs through fraud; both charges carry up to five years in prison and a $5,000 fine. He was released later in the day on a $5,000 bond.
